B30B PRESSES IN GENERAL (producing ultra-high pressure or ultra-high pressure and high temperature to effect modifications of a substance, e.g. for making artificial diamonds B01J3/00 )
Introduced: September 1968
Description
B30B covers mechanical presses of general application not specifically classified elsewhere in the B30 press category. This includes hydraulic, pneumatic, and mechanical pressing machines used for general industrial purposes such as forming, compacting, laminating, and assembling materials. The classification encompasses press mechanisms, control systems, and structural designs applicable across multiple industries, excluding specialized presses that fall under more specific B30 subclasses (such as B30C for metal-working presses or B30D for other particular press types). Inventions in this class typically relate to fundamental press designs, drive systems, and operational features of broad applicability rather than industry-specific pressing equipment.
